I found those videos very informative even though I stumbled upon them after I had bought my Brompton. I did order stuff from NYCE wheels (i.e. spare Easy Wheels, tire tubes, S-bar, etc.) and I find the guys very professional. After placing my order, I got a call and email followup from them because I ordered 2 pairs of what turned out to be Easy Wheels for the front part of the bike (with 6 mm mounting holes). I later found out that you need a different set of wheels for the rear with the smaller 5 mm mounting holes.
